Webrepresentations, [L1, L2, KaS] for quantum groups, [AuR, CB] for Kleinian singularities, [N1, N2, N3] for quiver varieties, and [GLS1, GLS2] for cluster algebras. For the case of proprojective algebras of non-Dynkin type, its tilting theory has been extensively studied in [BIRS, IR1]. In particular, they show that certain ideals parameter- Web1.4. Quotients. Our goal here is to show that the Kleinian singularities are actually quo-tients of C2 by the action of finite subgroups of SL 2(C). First, let us recall some general properties of quotients under finite group actions. Let X be an affine algebraic variety and Γ be a group acting on X by automorphisms. Then Γ also
